(TEMP SUMS: x = 505; 2 x² = 38,973) (NBR SUMS: 2 x = 527; 2 x² = 44,303)
The decision rule for this hypothesis test at a= 5% is:
a.
Reject Ho if the test statistic is less than the critical r value r
a = - 0.58.
b.
OD.Reject Ho if the test statistic is less than the critical r value r a = - 0.67.
OC: Reject Ho if the test statistic is greater than the critical r value r
= 0.58.
d.
O Reject Ho if the test statistic is greater than the critical r value r
0.67.

e.
Reject Ho if the test statistic is either less than the critical r value r a =- 0.75 or greater than the critical r value r
